First thing, forget that its a rock. Now, look at the detail on the piece. Study it like you were in an art gallery looking at a painting that you just can't "get" but want to..
Remember the whole time doing this: it's a canvas,not a rock and use your imagination. This goes for any interesting rock one may find.

It is a simple rock...

Yep, that's a rock.

River cobble, maybe limestone, w/ a little calcite an sulpher, maybe?

 

[hvacker]

A little scratch test, a tad of HCl, streak maybe

Rockhunter and hvacker bring up good points. I'll add that it looks similar to chert I've found in Missouri as a kid due to the fracturing. Hardness test and some chipping to see if it flakes out or crumbles will help determine if its in line with limestone or chert, ie a harder silicate. I dont see sulfur but calcite its possible.
